Hi, I can't repro this @austinmw . I have Ubuntu 22.04.2, I tried exactly the same commands and I can install faiss-gpu successfully:

conda create -n tester_env python=3.10
...
conda activate tester_env
conda install -c pytorch -c nvidia faiss-gpu=1.8.0

==> WARNING: A newer version of conda exists. <==
  current version: 4.10.1

Please update conda by running

    $ conda update -n base -c defaults conda

Proceed ([y]/n)? 

in your error log, it looks like the conda satisfiability solver found some conflicts. Could you double check if you are not creating the new env on top of an existing env that causes this?
